const analyticsConfig = {
  AWSPinpoint: {
    // Amazon Pinpoint App Client ID
    appId: Config.AWS_PINPOINT_APP_ID,
    // Amazon service region
    region: "us-east-1",

(attributesJson[“tenantId”] = sessionData.tenantId.toString()) : null; sessionData.tenantDto ? (attributesJson[“tenantname”] = sessionData.tenantDto.name.toString()) : null; }

Analytics.record({
